The conjugate base is the ion or molecule remaining after the acid has lost a proton, and the conjugate acid is the species created when the base accepts the proton.

The acid becomes the conjugate base.
The base becomes the conjugate acid.

I'm assuming H2O is the acid, so the answer I'm predicting is (C).
